1. I exist
2. My senses sometimes work
3. Objective physical evidence is a valid way of justifying beliefs
The last one is not something that everyone necessarily accepts. Pure rationalists may reject it (if there are any these days). But I just thought I'd pop in and say that you have basically stumbled on to the
'Three Primary Truths':
quote:
They are the first fact (the fact of our existence), the first principle (the principle of non-contradiction) and the first condition (the ability of the mind to know truth).
I don't have anything to add to the meat of your post at this time which basically seems to address parsimony and empiricism, but I thought you might be interested in that little tidbit.
